18 Oct 2011: Study of CO2 ‘Supply Line’ Urges Carbon Price at Point of Extraction A study quantifying each nation’s contribution to global carbon emissions based on its role in the supply chain of energy production — from resource mining to burning of fuels — suggests that pricing carbon at the point of extraction would simplify global efforts to curb emissions . In an analysis of global data on the trade of fossil energy resources, researchers found that extraction is highly concentrated, with seven nations (China, the U.S., Russia, Canada, Australia, India, and Norway) and the Middle East accounting for more than two-thirds of the world’s resources of oil, gas, and coal. According to the authors, enacting carbon pricing mechanisms at the point of extraction would prevent the relocation of industries, which would likely occur if regulations were put in place at the point ...
